into their operative and inoperative positions by any suitable source of power.

Another object of my invention is to provide a protector device along the opposite sides of the hull of a ship, the said device being movable. vertically to compensate for tides, etc., and also being movable away from the hull to its extended or operative position, and alsov being movable toward the hull to its collapsed or inoperative position in abutting relation to the sides of the ship.

Still another object of my invention is to provide a new and improved protecting device which can be installed and incorporated into any standard ship or boat of any size or type, without the necessity of changing or altering the structure of such ship or boat. Numerous additional objects of my invention will be set forth in the annexed description and drawings, which illustrate a preferred embodiment thereof.

Fig. 1 is a side elevational view 'of a ship equipped with the improved protecting device, the said device being shown in collapsed position or brought in againstthe hull.

Fig. 2 is a top plan view of the ship and the protecting means shown in Fig. 1.

Fig. 3 is an enlarged fragmentary side elevation of the ship and the protecting device, the said device being shown in the extended or operative position.

Fig. 4 is a sectional view on the line 4-4 of Fig. 3, a fragmentary portion of the ship being shown in top plan.

Referring to the drawings in detail, the reference letters A indicate the ship, H the hull thereof, B the bow and S the stem.

The improved protecting device includes the side protecting devices D and DD, and the means for controlling the movements thereof.

Contrivances D and DD are identical in construction and operation and each of said devices is arranged and movably positioned along the opposite sides of hull H.

Each of devices D and DD includes a plurality of U-shaped arms I which are movably mounted on vertical bars II by looping or bending the free ends of the horizontal portions of said arms Ill about said bars H. In this manner, arms ID are movable vertically on bars II and said arms II) are also swingably movable to and away from hull H. Each bar H is held in its vertical position by a coaxially aligned pair of rings or staples l2 which are driven into or secured to the opposite sides of hull H as shown in Figs. 2 and 4; each of said rings l2 being located adjacent the vertical end portions of each of said bars II. To prevent bars H from slipping through rings l2, the top end portion of each of said bars is bent at an angle with respect to the vertical por-' tion thereof, to form the lateral horizontal terminal l3 and the bottom end of said bars is provided with the nut N, the top face of said nut abutting the bottom face of lower ring 12.

Each U-shaped arm I0 is identical in construction and configuration. It will be noted that the free ends of the horizontal portions of these arms after being looped about bar H are provided with the integral terminal projections l4. These projections I4 act as stops which limit the swingin movement of arms In away from hull H. In the operative or extended position, projections I4 are parallel to hull H and in the collapsed or inoperative position said stops are perpendicular to the hull. This is clearly illustrated in Figs. 2 and 4. The function and operation of these projections M will be hereinafter explained more fully.

It will be noted from Figs. 1 and 2, that I include in my protective device five U-shaped arms [0 on each side of hull H. However, I do not wish to be limited to any particular number as" this may be varied as desired depending on the size of the ship. a

As shown in Fig. 1, the upper horizontal portion of each arm ID has a chain or cable l5 secured to it, the opposite end of said chain being secured to the railing [6 on the deck of ship A, one of said railings being provided on each side of the ship. These chains I 5 are employed whenever it is desired to hold arms l0 in raised vertical position to compensate for tides, varying water levels, etc.

Running parallel cables I! connect all of the U-shaped arms Ill on each side of hull H so that said arms will move in unison. This is accomplished by connecting said cables I I to said arms adjacent the ends of the vertical portions thereof in any suitable manner, as for example, by passing the cables around the same. Secured to cable I! intermediate arms ID are the vertical ings, the ends of upper and lower cables I! on each side of the ship are brought together and pass through rings or staples l9 secured on opposite sides of bow .B. Each pair of cables H from both sides of the ship then pass on to the deck of ship and all four cables are brought together and pass through ring or staple 23 secured...

to the deck adjacent bow B.

Referring now to the stern portion of the ship and also to Figs. 1 and 2 of the drawings, the ends of upper and lower cables I! on each side of the ship are brought together and pass through rings or staples 20 secured on O posite sides of stern S. Each pair of cables from both sides of the ship pass on to the .deck of the ship and-all four cables are brought together and pass under ring 24 secured to the deck adjacent stern S.

Mounted on each end of the ship are the elec'- tric or other suitable motors Ml and M2, motor Ml being located near the bow of the ship and motor M2 being located near the stern. Said motors are operatively connected by suitable gearing with the drums 21 and 22. Motor Ml drives drum 2| and motor M2 drives drum 22.

Motors Mi and M2 furnish the motive power necessary to move devices or gates D' and DD into their extended operative positions and to return the said devices to their inoperative or collapsed positions. Motor M2 is employed to move devices D and DD into their operative positions and motor Mlis employed to return the said devices. to their inoperative positions.

Figs. 1 and 2 show the protective devices D andDD in their inoperative position. To move the said devices into their operative positions, motor M2 is started thus driving drum 22. The rotation of said drum 22- causes all four cables 11' to Wind up thereon, thus moving the said cables along the opposite sides of hull H towards stern S in the direction shown by the arrows b in Figs; 1 and 2 until devices D and DD are in the extended or operative position shown in dotted lines'in Fig. 2 and in Figs; 3 and 4. It will be noted from Figs; 2'and 4 that arms Hi are prevented from moving beyond an angle of ninety degrees bythe terminal projection stops M; In the full operative position, arms are perpendicular to the sides of the ship and stops 14 are parallel and abut the sides of the ship. Thus when a torpedo strikes any of the protective devices while in the extended operative position, it will be deflected by the said protective devices towards the bow B, as shown in dotted lines in Fig. 2.

To return the protecting devices D and DD to their inoperative or collapsed position, motor MI is started thus driving drum 21. The rotation of said drum 2| causes all four cables I! to wind up thereon, thus moving the said cables along the opposite sides of hull H, towards bow B, in the direction shown by arrows at in Figs. 1 to 4, until the protecting devices are in the position shown in Figs.v 1 and 2, that is until the said protecting devices are in abutting parallel relation to the sides of the ship.

Although there is shown and described herein a preferred embodiment of the invention, it is obvious that numerous changes in details may be made without departing from the spirit or scope of this invention. I have not specified the materials. from which the various elements and members of my protecting devices are made, but it is obvious that inview of: the primary purpose for whiclrmy improvedd'evices are intended, that any strong steelsor'armon'plate would be suitable or desirable;

What'is claimed is:'

1. A protecting device for the hull of a ship arranged on opposite sides of said hull, comprisinga plurality of vertical bars securedtosaid hull, an arm mounted on each of said barsland being movable thereon, a plurality of cables connecting said arms, a plurality of deflector bars secured to saidca'bles intermediate each of said arms, means carried by the ship for moving said cables and arms toward and away from the sidesof the ship; at least one ofv said arms being provided with means to limit the outward movement' of said arms-from thesides ofthe ship.

2; A protecting device for the hull of a ship comprising protective units arranged on opposite sides of said hull, each of said units including a plurality. of vertical bars secured to said hull, a U-shaped arm movably mounted on each of said bars,,a pluralityof' parallelcables connecting said U-shaped arms, a plurality of deflector bars secured to'said cables intermediate each of said U-shaped arms, said deflector bars being parallel to the vertical barsand the U-shaped arms, means carried. by. one end ofthe ship for moving said cables and U-shaped' arms away from thesides. of-the ship,.means carried by the opposite end of saidship. for moving said cables andU-shapedarms towardsthe sides of theship, at least one of said. U -shaped. arms being provided with; stop means to limit the outward movement of said u-shapedarms from. the sides ofthe ship.
